Newton Distance S 9 Review

    The Distance and the Distance S are among the shoes I have always wanted to try, but never had or taken the opportunity. As someone who loves light stability shoes and racing shoes, I am a bit embarrassed that it took me this long to try the Distance S finally at version 9. A slowly narrowing category, this shoe is a unique one in regards to both stability as well as speed. I am excited the Distance S continues its legacy and think it is a great tool worth talking about!


Specifications (per Running Warehouse)
Weight: 7.8 oz (men's size 9), 6.8 oz (women's size 7)
Stack Height:  27 mm / 25 mm
Drop: 2mm
Classification: Mild Stability Lightweight Trainer 


HIGHLIGHTS

     The Newton Distance S 9 is a light stability lightweight trainer and distance racing shoe that should work well for a athletes looking for a fast and slightly firmer shoe. For those looking for a little more stability up front in a lightweight and fast package, this may be the shoe for you. With a super breathable, comfortable and well draining upper, this shoe works well both for road and triathlon use. A unique fast shoe with more forward stability, the Distance S 9 will work both for fast miles and training miles depending on your preference.

FIT

Matt: The New Distance S 9 fits true to size in my normal men's size 10. As Newton is a favorite among triathletes, the upper is very breathable, drains well (ran through a sprinkler for this) and is really comfortable against bare skin. This is one of the few shoes that I have absolutely no hesitation wearing without socks, although still be cautious if you are not used to this. The heel and midfoot fit fairly snug as expected in a uptempo shoe. The forefoot has a little bit more room compared to the rear, but is still normal to snug in width. The mesh in the forefoot stretches very well, so a variety of foot types should be able to use this shoe up front. The tongue is very comfortable and is secured by two minimal soft elastics that do a great job of holding it in place. There is a heel counter in the rear of the shoe, however it is low and padded. I did not have any issues with the heel counter and found the entire fit very comfortable. This shoe does fit a little snugger throughout as expected with a faster shoe, but should stretch for a variety of foot types.


RIDE

Matt: As with all Newton shoes, the Distance S 9 has prominent lugs in the forefoot. The lugs provide a very responsive ride at the front, while the full foot Newtonium cushioning provides some mild cushion at the heel. The ride is on the firmer and more responsive side throughout the length of the shoe. The heel drop is low at 2mm, so those sensitive to low drop should carefully transition into this shoe. The transition is actually pretty smooth no matter where you land as either landing on or transitioning onto the lugs still provides plenty of pop. The sole actually has some flexibility to it, but is most prominent after the lugs. This allows for a very smooth toe off (particularly at higher speeds) and promotes bending of the sole at the correct place! There is a decent and gradual heel bevel present, which combined with the slightly softer foam and design in the rearfoot makes for smooth, albeit low landings given the low stack height and drop.


SPEED

Matt: Newton shoes are already fun to pick up the pace in and the Distance S 9 is no different. This is a really fun shoe to run fast in.  The forefoot lugs are very responsive and make getting up onto your toes easy. Combined with an internal plate and a smooth toe off, this shoe will go as fast as you push it. The Distance S 9 excels at faster workouts and tempo runs thanks to the high level of responsiveness and lug design. I have used this shoe for hill repeats, 400m repeats and tempo runs and the Distance S 9 has done very well with all of them. There is enough cushioning for uptempo longer efforts if you get your body used to the slightly firmer ride and lower drop. Experienced runners may be able to use this as a training shoe if they tolerate this type of shoe for mileage. Most people will find this a mild stability workout and racing shoe for 5k to half marathon or beyond if you are used to the drop. For those used to lower drop shoes, this will easily be a racing shoe for marathon distances. Overall this is a fast shoe that can handle a variety of paces, although only those experienced with this shoe will be able to train in it full time or take it to marathon distances.

STABILITY

Matt: Newton shoes are very stable whether they are neutral or not thanks to a plate that is included in the sole. The Distance S 9 also has medial posting in the forefoot and midfoot, providing additional mild stability. The post is not aggressive and is integrated very well into the midsole. This does add a little extra firmness in the midfoot and forefoot. The five lug configuration also provides a wider base, which further improves the stability. What the forward stability does well is center the shoe for very nice and efficient toe offs. Running fast in this shoe is really fun because everything feels very comfortably controlled. The stability is mild, but still solid enough to hold things together for long miles.

DURABILITY

Matt: As a lighter weight running shoe, the outsole durability on the Distance S 9 is not the greatest. I am already seeing extensive wear on the anterior portion of the lugs. The posterior lateral heel is beginning to show wear and I am only at 43 miles. This however is expected with a lighter weight shoe. The midsole and upper though have remained untouched. The upper has zero seams loose, still fits like new and is still very comfortable (no break in required). The midsole has almost no signs of creasing (despite some fast miles in these) and still feels comfortable. So overall decently durable for a lightweight trainer/racer, although I expect a little less than industry standard (300-500 miles) out of these. 


THOUGHTS AS A DPT

     I appreciate that Newton has moved away from promoting a certain type of footstrike. There is plenty of literature out there to support that injury rates are not different between the different types (Hamil & Gruber 2017). The types of injuries however are different as each one loads different tissues (Anderson et al., 2017). Additionally, there are no differences in efficiency except when you look at sprinting middle distance events (Hayes & Caplan, 2010), which makes sense given that footstrike often changes with speed (Hasegawa et al., 2007).


     What the lugs do provide is a great pivot point and an opportunity for a forefoot cushioning mechanism. Most companies still put most cushioning technologies in the heel, which again is appropriate given the higher percentage of heel first initial contact athletes. What is often forgotten is that the forefoot can still make a hard contact with the ground. For certain athletes, a more protective front part of the shoe may go a long way for the amount of force generated through toe off, sprinting, etc. Newton has been unique in this regard and I hope other companies start thinking a bit more about what happens in regards to protection at the front of the foot. 

 


RECOMMENDATIONS

Matt: The Newton Distance S 9 is a tool that will fit a unique population of runners. This could be broadened with the addition of some additional heel cushioning like the Kismet (REVIEW) and Fate (REVIEW) have. We know that most of the population are heel strikers and even elite athletes use a variety of footstrikes (Kamser et al., 2013; Larson et al., 2011). So to open this up to a larger population, addressing the heel may be important.

Although I recognize this is a racing shoe, some additional outsole rubber on the heel and at the lugs may be helpful for durability. However this may not be worth it if the expense is heavier weight. 

CONCLUSION

Matt: The Newton Distance S 9 is a workout, racing, and lightweight trainer for those who want a lower drop, faster and very stable shoe. The lugs, sole design and lighter weight provide a snappy and fast ride that works well for speed workouts to longer tempo runs. The stability will work well for a variety of people given both the mid/forefoot posting and inherently stable design. Although a little on the firmer side, those experienced with low drop shoes will find a shoe able to handle 5k speed all the way to the marathon. For others, this is a unique training tool for lower extremity strength and exposing the body to something a little different.

GRADING
